Tie-1 tyrosine kinase expression in human thyroid neoplasms
Histopathology
|March 31, 2004
Summary
Tie-1 expression is linked to early papillary thyroid cancer development but not to advanced anaplastic or follicular tumors. This receptor-type tyrosine kinase (RTK) plays a role in thyroid tumorigenesis.
Area of Science:
- Oncology
- Molecular Biology
- Endocrinology
Background:
- Receptor-type tyrosine kinases (RTKs) are implicated in carcinoma progression.
- Tie-1, an RTK, is known to influence angiogenesis.
- The specific role of Tie-1 in human carcinoma, particularly thyroid neoplasms, requires further investigation.
Purpose of the Study:
- To examine the expression patterns of Tie-1 in various human thyroid tumors.
- To determine the potential role of Tie-1 in the pathogenesis of thyroid neoplasms.
Main Methods:
- Immunohistochemical analysis was employed to detect Tie-1 expression.
- The study included normal thyroid tissue, papillary carcinoma, anaplastic carcinoma, follicular carcinoma, and adenoma.
Main Results:
- Tie-1 immunoreactivity was infrequent in normal thyroid follicular cells.
- Tie-1 was expressed in 55.7% of papillary thyroid carcinomas, particularly in smaller tumors without poor differentiation.
- Expression was significantly lower in anaplastic carcinoma (8.3%) and absent in follicular carcinoma and adenoma.
Conclusions:
- Tie-1 expression suggests a role in the early stages of thyroid tumorigenesis, specifically in papillary carcinoma.
- Tie-1 does not appear to be a significant factor in the progression of anaplastic carcinoma or follicular tumors.

01:00Enzyme-linked Receptors
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:26Receptor Tyrosine Kinases
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
01:23The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
